Let's see if I can help any.

I don't know a whole lot about these suspension systems but I do know a little which may help you. With that system you can sometimes depending on what materials are used lighten up the front end. Leaf springs are pretty heavy and if engineered correctly with the right materials the multi point suspension systems in question can be lighter.

You need three things: A track bar, which laterally locates the axle between the frame rail and the main suspension arms, whether it be two arms or four and coils, coilovers, whatever. Adding mounts to the frame for all of these things will be 100% custom and pricey depending on whose doing it. That's probably why a lot of people generally stay away from this but it has been done, i've seen it and when done correctly it's bad ass!!

The main reason I can think to avoid this is because you need to understand a little thing called anti squat. I really don't know much about this but i'll try...drag racers would probably be the best source for this. When accelerating you want the suspension to force the axle into the ground for increased tire contact, not enough anti squat and the suspension will suck the tires up...less force being applied to the tires. There is a ratio, which not everyone agrees on btw but in order to find it you need either to take some measurments from your vehicle or if you're in the planning stages draw diagrams and figure out a few measurements. You have to draw out a few lines, one through the center of gravity, then you need to find the vehicles instant centers, force vectors and using all of that you need to find out how much anti squat there is. The ratio is usually expressed in a percentage.

A few years ago I was very interested in designing something like this for my old ford truck so I didn a bunch of research but as you can tell i've forgotten it. If you do something like this, do your research, it's a lot of information.
